AC current sensor error

What does 315 mean?

This code indicates an error with the AC current sensor. This sensor is crucial for measuring the current being fed into the grid and for protective functions. An error in this sensor causes a short-term interruption in energy feeding.

• Malfunction of the internal AC current sensor hardware.
• Disconnection or damage to the AC current sensor wiring.
• Fault in the associated signal processing circuitry.

Click steps to track your progress.

1. 1

   If the status code is displayed continuously, notify a Fronius-trained service engineer for inspection and repair.

2. 2

   Perform an AC reset to rule out transient sensor errors.

3. 3

   Verify all internal connections related to AC current measurement are secure.
